The wikipedia entry for the A380 gives the maximum range at design load as 15,700 km. The equivalent entry for a Boeing 747-400 gives around 14,000 km but distances of 18,000 km have been performed in demonstrations. So I infer the ferry range for the A380 would be even higher. Is it specified anywhere? Has a flight by an A380 in excess of 15,700 km been performed to date? Could it fly between any two airports on Earth?
